I am not a big gun person, but I do play quite a few FPS gun games. In most of them the guns have multiple accessories. One of the biggest accessories that I have seen on the guns in the games that I play is a holographic sight kind of similar looking to the eotech magnifier pictured below. As a matter of fact in Call of Duty Black Ops you can even customize the colors, and shapes in the holographic sight. What I don’t understand is the need for “holographic” images instead of the real thing. When you are shooting you aren’t shooting holograms, so what is the purpose?
Keep in mind that I am a total rookie when it comes to guns, so please don’t think that I am asking a stupid question. I am only asking because I honestly don’t understand.
